Application-Specific Cache and Prefetching for HEVC CABAC Decoding

Habermann, Philipp ; Chi, Chi Ching ; Álvarez-Mesa, Mauricio ; Juurlink, Ben (2017)

Context-based Adaptive Binary Arithmetic Coding (CABAC) is the entropy coding module in the HEVC/H.265 video coding standard. As in its predecessor, H.264/AVC, CABAC is a well-known throughput bottleneck due to its strong data dependencies. Besides other optimizations, the replacement of the context model memory by a smaller cache has been proposed for hardware decoders, resulting in an improve...

Optimizing HEVC CABAC decoding with a context model cache and application-specific prefetching

Habermann, Philipp ; Chi, Chi Ching ; Álvarez-Mesa, Mauricio ; Juurlink, Ben (2015)

Context-based Adaptive Binary Arithmetic Coding is the entropy coding module in the most recent JCT-VC video coding standard HEVC/H.265. As in the predecessor H.264/AVC, CABAC is a well-known throughput bottleneck due to its strong data dependencies. Beside other optimizations, the replacement of the context model memory by a smaller cache has been proposed, resulting in an improved clock frequ...

Film265: Report on Achieved Quality Improvements

Álvarez-Mesa, Mauricio ; Sanz-Rodríguez, Sergio (2016-06-30)

This document presents the results of the informal video quality subjective tests performed in the context of the Film265 project. In this project a new implementation of the HEVC/H.265 video coding standard has been developed, which obtains higher quality and higher compression efficiency than previous codecs such as the H.264/AVC, and other implementations of the HEVC/H.265 encoder (such as t...
